SPECIFICATION forming part of Letters Patent No. 788,577, dated May 2,1905.

Application filed March 29, 1904. Serial No. 200,852.

To all whmn it may concern.-

Be it known that I, GEORGE BAss BLACK- MAN, a citizen of the UnitedStates, residing at Chattanooga, in the county of Hamilton and State ofTennessee, have invented a new and useful Veterinary Injector, of whichthe following is a specification.

This invention relates to devices for treat ing air or other gases forcharging the same with other elements or for extracting certainpredetermined elements therefrom, and has for its object to simplify andimprove the construction and produce a device of this character adaptedfor a variety of purposes and which may be manufactured at small expenseand in portable shape.

With these and other objects in view, which will appear as the nature ofthe invention is better understood, the same consists in certain novelfeatures of construction hereinafter fully described and claimed.

1n the accompanying drawings, forming a part of this specification, andin which corresponding parts are denoted by like designating characters,is illustrated the preferred form of the embodiment of the inventioncapable of carrying the same into practical operation, it beingunderstood that the invention is not necessarily limited thereto, as various changes in the shape, proportions, and general assemblage of theparts may be resorted to Without departing from theprinciple of theinvention or sacrificing any of its advantages, and the right istherefore reserved of making all the changes and modifications whichfall within the scope of the invention and the claim made therefor.

1n the drawings thus employed, Figure 1 is a sectional longitudinalelevation. Fig. 2 is a transverse section on the line 2 2 of Fig. 1.

The improved device is adapted fora variety of purposes and for treatingair or other gases in a variety of ways, but will generally be employedfor medicinal purposes as, for instance, in treating cows for parturientparesis or apoplexy, commonly called milk fever, to which it is moreparticularly adapted-and by means of which the udders can be readilyinflated with oxygen gas, and for the purpose of illustration theimproved device is shown arranged for the above or a similar purpose.

The improved device consists of a receiver 10 of any suitable size ormaterial, having a relatively high cover 11 detachably connected, as byscrew-threads, at 12. Supported in the receiver 10 at an intermediatepoint is a foraniinous diaphragm 13, preferably detachable from thecasing to provide for the introduction of the charging and sterilizingmedium or compound into the receiver. The diaphragm will preferably beprovided with a ring -frame 14, resting upon an annular bracket 15, bywhich means it may be readily supported detachably within the receiverat any desired point, as determined by the location of the bracket.Supported intermediate] y within the cover 11 is another foraminousdiaphragm 16, spaced from the diaphragm 13 within the receiver and alsospaced from the upper side of the cover member, whereby the apparatus isdivided into three compartments-a lower compartment beneath theintermediate diaphragm 13 for the charging compound, an intermediatecompartment between the two diaphragnis for an absorbent or filteringmedium or material, and an upper compartment Within the cover above theup per diaphragm, in which the charged air, gas, or other fluidaccumulates after passing through the absorbent material.

The means for inducing the passage of air or other fluid to be chargedthrough the sterilizing and filtering mediums consists of a pipe 17passing through the wall of the receiver and terminating near the bottomof the same and provided exteriorly with a nipple 18, to which a sectionof hose 19, having an air-bulb 20 of the ordinary construction, isattached.

The cover 11 is provided with a nipple 21, to which a section of hose 22is attached, terminating in a discharge nozzle or needle 23 or othermeans for conducting the charged gas to the affected parts.

When it is desired to discharge oxygen gas from the member 23, a supplyof peroxid of hydrogen is placed in the receiver-compartment beneath thediaphragm 13 and the inter mediate compartment between the diaphragmssupplied with absorbent material, such as antiseptic cotton. thecompound in the receiver by compressing thebulb 20, the compoundremoving deleterious germs or foreign matter from the air and settingfree the ozone, which passes through the antiseptic mass between thediaphragms and thence passes as pure ozone to the conductor-hose 22 anddischarge member 23. The air is thus thoroughly sterilized andasepticized and passes to the affected parts in the best possiblecondition to produce the desired results. All dangerof infection is thusobviated, and as the udders of cows, as well as other parts which mayrequire the treatment, are verysusceptible to infection from diseasegerms the apparatus above described will be found very efiicacious intreating diseases which can be reached thereby.

Of course it will be understood that compounds and materials other thanthose enumerated may be employed in the receiver and between thediaphragms for producing other effects or results than those citedwithout departing from the principle of the invention.

By this simple arrangement shown it will be obvious that the mass ofabsorbent material may be tightly compressed in the com- Air is thenforced through partment between the diaphragms by merely screwing thecover down upon the receiver.

By this simple device a farmer or stockraiser can have at hand aconvenient and readily-operated device whereby diseases of the classnoted can be quickly and easily treated and at small expense and withoutthe necessity for delay incident. to calling in the services of aveterinarian or other practitioner.

Having thus described the invention, what is claimed is- A device of theclass described comprising a receiver to contain a sterilizing liquid,spaced foraminous diaphragms disposed above the liquid, anantisepticized f ltering medium arranged between the diaphragms,anihjb't' ing-nozzle operatively connected with the device above thefilter, and means for forcing air through the liquid and the filteringmedium and through the nozzle.

In testimony that I claim the foregoing as my own 1 have hereto aflixedmy signature in the presence of two witnesses.
